Each step in the concentration of an ore adds to the cost of the operation, and unless the value of the additional mineral recovered exceeds the extra cost of recovering it, the refinement is obviously uneconomical. ... Electrostatic separation also is employed sometimes, principally in dressing nonmetallic minerals. Although the best …

Magnetic separator is the basic tool used by mineral processing plants to separate ferrous and non-ferrous metals from extracted ore, ensuring high-quality final products. Its works by attracting magnetic particles such as iron, steel and nickel, and then using powerful magnets or electromagnets to separate these particles from other materials.
